An excellent weekend enjoying the lowlands.
I felt a fair bit of pressure on the Audax day around timings to get round a 200km route and have an enjoyable time... the frequent town sections whist pretty we very slow sections and not audax friendly... something to watch out for and avoid next time I think. Also an observation from what worked well on other tours was when we stop, gather everyone together and agree what time to leave.. we failed to communicate as a group a couple of times which could have upset the apple cart if we weren't all sort of used to each other already!
The second day was less pressured but still had a timing pressure due to the boat, so it still felt a bit rushed (even when you remove the fast riding out of the equation).
My thoughts are it would be better to ride out on the day off the boat and Audax the following day, then ride back to the boat a day after that. This would also accommodate anyone who wanted to come along and not ride a 200km as they could do their own thing on the middle day.
The problem with a 3 day is it might require a Thursday evening crossing, riding 200km on a Sunday over there might not work out for logistics, however a Thursday crossing might be cheaper?
From my experience now, we were on the limit of enjoyable time with the 130km route back I think some of that can be mitigated by eating on the boat, but also understand that might not suit everyone, perhaps an earlier food stop before the last 30km or so would work better (i.e. Fat Mermaid on the return worked well on one ride back to the boat for me.) - I am so glad we didnt do the longer versions of the D2 route, it would have ruined the weekend because of even more time pressure to get back..
Personally, I am gravitating to no more than 100km a day, may be 120km at a push to transition to where we might want to start a 200km. This allows for a nice touring/audax pace with some good stops to refuel, though probably longer abroad, but why wouldn't you want to spend longer over there!
